Description

A flaw was found in the Linux kernel's Host1x bus driver. This vulnerability can lead to a Denial of Service (DoS) by causing a system crash. During device initialization error handling, the driver attempts to access client operations without first verifying their presence. A local user capable of triggering these initialization failure conditions can cause a null pointer dereference that halts the operating system.
